W-fi not working on Macbook pro 9.1

Created by: londere

Hi, after update xanmod kernel on 5.6.6-xanmod1, the system starts normally after getting in the OS, the network manager does not see the wifi adapter (Broadcom Inc. and subsidiaries BCM4331 802.11a/b/g/n), if I try sudo modprobe b43 the system enables the wireless adapter but it dosent connect to the 5Ghz Wifi network.

CPU: Intel Core i7-3720QM GPU : Intel 3rd Gen Core processor Graphics Controller / NVIDIA GeForce GT 650M Mac Edition @ 440.64 Driver (NO CUDA) Desktop: Mate 1.24.0
